You are never too young to wear a cape
The suit itself is really soft to touch which is great for newborn skin and length wise it must be quite long as F's weight comes from his longer than usual length (96th percentile).
To save marking their face and to keep their hands warm there is integrated scratch mittens built into the sleeves of the suit.
The design on the front of the suit is mainly embroidered on which is great as it adds to the quality of the outfit (The S of the design is printed on although the outline of the badge is also embroidered).
Such a fun wee suit and cute on any little super hero.
